However, it’s believed that thousands and thousands of FRBs reach Earth every single day. Just like any phenomenon that is not widely understood in space, many people believe that FRBs are messages from extraterrestrials or beacons from an interstellar alien spaceship. It’s certainly not impossible, however, there’s not much to support that, other than wishful thinking.
One possible explanation is that they are the “bangs” of a collision between very dense objects, such as merging black holes or neutron stars. Alternatively, they might have sprung from an especially energetic supernova. Nevertheless, if scientists can work out more precisely where these FRBs originated, the hope is that they could discover what’s causing them.
